Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

The surprising discovery of superconductivity in layered iron-based materials, with transition
temperatures climbing as high as 55 K, has led to thousands of publications on this subject …

The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

High-temperature superconductivity in the iron-based materials emerges from, or sometimes
coexists with, their metallic or insulating parent compound states. This is surprising, as these …

High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

In a superconductor electrons form pairs and electric transport becomes dissipation-less at
low temperatures. Recently discovered iron-based superconductors have the highest …

Since the first report on superconductivity at 26 K in F-doped LaOFeAs at the end of
February 2008, the iron pnictide superconductor family has been quickly expanded to six …

We present a combined high-resolution x-ray diffraction and x-ray resonant magnetic
scattering study of as-grown BaFe 2 As 2. The structural and magnetic transitions must be …

Since the discovery of the metallic antiferromagnetic (AF) ground state near
superconductivity in iron pnictide superconductors,,, a central question has been whether …

Neutron diffraction studies of Ba (Fe 1-x Co x) 2 As 2 reveal that commensurate
antiferromagnetic order gives way to incommensurate magnetic order for Co compositions …
